Verified step by step guidance

Understand the function of rods in the retina: Rods are photoreceptor cells in the retina that are highly sensitive to light and are primarily responsible for vision in low-light conditions.

Compare rods to cones: Cones are another type of photoreceptor cell in the retina, responsible for color vision and visual acuity in bright light conditions. Unlike rods, cones are less sensitive to low light.

Identify the location of rods: Rods are distributed throughout the retina but are absent in the fovea centralis, which is the area of the retina responsible for sharp central vision and is densely packed with cones.

Evaluate the light conditions for rod function: Rods function optimally in dim light conditions, making them crucial for night vision, whereas cones function best in bright light.

Determine the correct statement: Based on the understanding of rod functions and characteristics, the true statement is that rods are more sensitive to light than cones.
